To all whom it may concern:

Be it known that I, JoKo Jonen DA SIL- VEIRA E PAULO, a subject of the King of rotation of the 1 provided with charging doors '5 and inspec- It will be obvious that the cylinder (i will agitate or distion doors 6.

Portugal, and resident of Lisbon, Portugal, place the contents of the compartments 0 in have invented a certain new and useful Improvement 1n Machines for Drying Cocoa, of

which the following is full, clear, and exact be necessary description.

This invention relates to improvements in machines for drying cocoa and has for its object the provision of a machine in which material of this character can be effectively and quickly dried and readily inspected by the operator.

The invention will be more fully described in connection with the accompanying drawof ings and will be more out and ascertained in claim.

In the drawings :-Figure l is a view partly in elevation and partly in section illustrating a machine embodying the main features of my invention. Fig. 2 is a transverse sectional view thereof. Fig. 3 is an end elevation thereof. Fig. 4- is an end view with parts omitted to show the internal mechanism. .Fig. 5 is ardetail perspective view of one of the compartments for containing the cocoa.

Like characters of reference designate similar parts throughout the different figures of the drawings.

As shown in the drawings (Z designates a cylinder, which may if desired be made up of a plurality of sections, and which is secured to a shaft 9 mounted in suitable bearings 25. The cylinder d may be rotated by the application of power to the shaft 9 in any desired manner not shown. The cylinder (1 is composed of a metallic frame provided with a peripheral wall of foraminated material so as to permit free circulation of the drying medium. A plurality of longitudinally disposed compartments 0 are secured in the side of the cylinder 01 in a manner to project radially inwardly from the cylindrical wall. Said. compartments are arranged in parallel relation and are spaced apart from each other a sufficient distance to permit passage of the operator when charging and removing the cocoa from the compartments. In order particularly pointed and by the appended that cocoa may be effectively subjected to an effective manner so that no supplemental or auxiliary stirring or agitating means will A casing a is shown surrounding the cylinder (Z for the purpose of inclosing the same and retaining the drying medium so that the same will act upon the contents of the compartments 0. Means preferably in the form of a coil or pipe or is disposed within the casl l mg a and mainly connected w1th a source of supply of steam (not shown) for the purpose heating the air within the casing. Any suitable form of discharge (not shown) may be provided and the source of supply of discharge may be regulated by valves in any well known manner.

Drainage for condensed vapor may be provided by providing the casing a with a plurality of openings f discharging into suitable outlets hereinafter described. The casing a, is provided with closable openings 0, p and n for the purpose of admitting air when the drying operation has been completed and also for the purpose of changing, or supplying fresh air, to the casing during the drying operation.

The cylinder of may be provided with doors a arranged abreast of the compartments 0, and the spaces therebetween, so that access may be had to any of the several compartments.

I desirably mount the casing a in a longitudinally concave support of masonry or other suitable material and in the lower portion thereof longitudinally disposed drainage grooves are formed and as shownsaid grooves are made relatively deeper fromthe ends of the supports .5. Transversely disposed tubes 7L communicate with the grooves g and may conveniently be opened and closed by taps o.

I claim A cocoa drying device comprising in combination, a concave masonry provided with a longitudinal drainage groove gradually deepwith said groove to discharge the contents therefrom, a cylindrical casing seated in said support and provided with discharge openings delivering to said groove, air doors for said casing, a heating coil for said casing, an

transverse drainage tubes communicating rality of radially disposed inwardly projectoperating shaft extending through said casdoors for said cylinder adjacent said casing mg, a foraminated cylinder mounted on and doors. rotated by said shaft and located Within said Y casing, said casing being provided with a pln- JOAO JORGE DA SHAMRA PAULO Witnesses MANUEL CARREIRO IoNEeo,
